Abstract: A method of optimizing drill bit design and an optimized drill bit for drilling a well into an earth formation comprising a bit body; a number of blades spaced around the bit body, each blade having a curved outer edge and a forward face; a first row of cutter pockets recessed into the face along the outer edge of each blade; a second group of cutter pockets recessed into the face of each blade offset from the first row; and a plurality of cutting elements, each cutting element being brazed into a different one of the cutter pockets.

Abstract: Las modalidades descritas permiten a un usuario solicitar nuevos diseños de producto y cambios de diseño remotamente. El diseño o cambio solicitado se envía entonces a un proceso automatizado basado en red. El proceso puede accesarse remotamente por el usuario a través de una conexión de red. En una modalidad, puede reunirse directamente con un el cliente, obteniendo las especificaciones para el producto en cuestión, seleccionar un diseño o cambio deseado por el cliente, y enviar el diseño o cambio. El proceso trabaja en los antecedentes para validar el diseño solicitado de acuerdo con una o más reglas de validación y/o mejores prácticas, y completa varias de las tareas necesarias para hacer posible que se proceda con el diseño solicitado para fabricar. Una vez que el proceso ha completado exitosamente el cambio solicitado, se envía una notificación al usuario que contiene información acerca del producto cambiado o nuevo, tal como el nuevo número de parte, número de orden, y similares.

Abstract: Methods of forming polycrystalline diamond elements include forming a polycrystalline diamond element. A Group VIII metal or alloy catalyst is employed to form the polycrystalline diamond compact table at a pressure of at least about 6.5 GPa or greater. The catalyst is then removed from at least a portion of the table to a depth from a working surface thereof, and may be removed from the entirety of the table. Polycrystalline diamond elements include such polycrystalline diamond compact tables. Earth-boring tools include such polycrystalline diamond elements carried thereon and employed as cutting elements.

Abstract: A rotary drag bit including exterior features to control the depth of cut by cutters mounted thereon, so as to control the volume of formation material cut per bit rotation as well as the torque experienced by the bit and an associated bottomhole assembly. The exterior features preferably precede, taken in the direction of bit rotation, cutters with which they are associated, and provide sufficient bearing area so as to support the bit against the bottom of the borehole under weight on bit without exceeding the compressive strength of the formation rock. The exterior features may be oriented and configured to function optimally at a predicted rate of penetration, or range of rates, at which the bit may be operated, such rate or rates being further optionally maximized in softer formations in light of the ability of the bit to hydraulically clear a maximum volume of formation cuttings to prevent so-called bit balling.

Abstract: L'invention fournit un trépan à l'éléments de coupe fixes ou un trépan rotatif à lame (10) pour le forage de formations souterraines, présentant une résistance améliorée à une agglutionation du trépan et un taux de pénétration amélioré. Le trépan (10) engloble une configuration des lames du type tarière, dans laquelle des lames relativement grandes, à inclinaison positive sont inclinées en rotation vers l'avant pour assurer un dégagement accru et un volume accru entre la face du trépan (16) et la formation, pour faciliter l'élimination des déblais sortant des sommets des éléments de coupe à partir de la face du trépan (16). Les lames (14) sont chacune pratiquement contigües à une plaquette de front de taille hélicoïdale allongée (40) inclinée en rotation vers l'avant, à la manière des lames (14), les longueurs longitudinales des plaquettes de front de taille (40) et des arêtes radialement externes (24) des lames (14), en combinaison avec leur inclinaison, établissant une structure de stabilisation, entourant presque complètement la circonférence du corps de trépan (12).
